Charge Box HFW

4Load HFW chargers are available in six designs. They are perfect for use in professional traction applications.

The HFW series is characterised by protection class IP66: Dust-proof and protected against pressurised jets of water. Another benefit: easy switch-over between special charging curves for wet-cell, gel and AGM batteries. The profile is rounded off nicely with protection against polarity reversal, short-circuiting, over-heating and surges.
